Purpose of the project

1. To provide long-term preservation of permanent record material and the state’s fine art collections in temperature and humidity

controlled environment;

2. To consolidate the storage of permanent record material and fine art collections;

3. To provide for the care and preservation of permanent electronic record material and stand up adequate disaster recovery /

business continuity infrastructure for critical, permanent electronic record material; and

4. To provide adequate access to the public through processing and scanning of record material;

5. To provide for the care and preservation of the State’s fine art collection through conservation treatment.

Project Scope This project contemplates the acquisition of an existing 170,000 + warehouse facility on the open market. The facility will then be renovated to provide appropriate levels of temperature and humidity controls and will be retrofitted with records center shelving from the existing warehouses and compact shelving to be acquired as part of the renovation. In our timeline featured in Volume I we have shown some renovation work overlapping with renovation design. This is because we are hoping that we can begin the process of building out compact shelving in one portion of the building while design and then installation of HVAC and other renovations proceed. Following installation of compact shelving, we will begin the process of transferring existing records to the new facility. At the same time we propose de-constructing the existing records center shelving at each of the warehouses and reconstructing it in the new facility. This would take place over the course of a one year period using prison labor. By utilizing a mix of compact shelving and leveraging our existing investment in existing records center shelving, we will be able to accommodate records currently housed at all of our warehouse facilities and will have enough space for anticipated records transfers through FY 2027.

General Characteristics of the Facility / Architectural and Environmental Considerations

The Maryland State Archives Facilities Program

Page 3 of 26

The purpose-built archives is designed and built with many unique criteria including:

ο Constancy of temperature and relative humidity. In order to achieve the desired storage conditions, the Archives adjunct facility

needs to be designed with the utmost consideration given to the development of mechanical systems that can adhere to rigorous environmental conditions. Specifically, the storage areas maintain stable and constant temperature and humidity levels;

ο Proper air filtration to remove pollution and such contaminants as mold spores. The ability of the mechanical systems to effectively remove particulate matter such as mold spores and other pollutants such as gases is particularly important;

ο Sturdy construction with adequate load bearing and the ability to deal with extreme conditions such as tornadoes and hurricanes;

ο A maximum fire rating for walls, roof, columns, floors etc., and minimum of combustible materials;

ο Specialized fire detection and protection for the storage areas;

ο Avoidance of many materials and finishing products that may be common to other facilities but may be damaging to records and art;

ο Adequate vapor barriers and insulation to inhibit moisture infiltration and to reduce thermal gain or loss;

ο A minimum number of windows and doors;

ο Adequate security including perimeter security; internal access and control systems; motion detection and security cameras.

The facility would include the following elements:

************************************* As outlined in the table of contents, the next section of this Volume will describe the characteristics of each individual spatial element of the facility. Following that section are a series of “Design Specification Guidance” documents which provide substantial additional information to provide direction to the consultant to be hired to superintend the design and renovation project. Additional documentation is provided in the form of the Program and Specifications document developed by the Department of General Services in April of 1981 to guide the design of the current Archives building in Annapolis. Much of the general design specifications and functional relationships remain the same so we thought this, too, may be of assistance.

Space Requirements: Description of each Element Space: Records Storage Area: 115,000 NSF Capacity: 390,000 cubic feet Function: Archival storage for the State’s permanent record material.. The calculations for the GSF / NSF of this proposed facility were based on known records in custody by cubic feet and the estimated accretion of 13,000 cubic feet of record material per year for roughly 15 years. The assumption was made that the new facility would utilize a combination of the same type of compact / movable shelving at the existing archives building and reconstructed records center shelving taken from the existing rented warehouses. Equip. (Fixed): To maximize space efficiency, the Archives recommends that a portion of the stack areas be constructed of the same type of compact shelving used at the Edward C. Papenfuse building in Annapolis. These mobile, high density units double the storage capacity of any given space by eliminating aisle space. Space conservation should be a consideration not just for the economic benefits of reduced construction costs, but also for environmental reasons. Mobile shelving offers environmental benefits by reducing ongoing energy requirements. More importantly, the tightness with which records are stored actually helps maintain their stability. Finally, they also aid in the retrieval of items given that less energy needs to be expended to get to the record material. To leverage existing investments in regular records center shelving, the Archives would also suggest that the shelving presently used at our rented warehouses, be taken down and reconstructed at the new warehouse. While this will entail considerable labor, we hope to be able to utilize work crews from the prison system to keep the cost reasonable. Equip. (Movable): Storage and retrieval records carts and trucks; steps ladders Utilities: A review of the lighting and fire detection / suppression systems would be in order. Telecomm: Data jacks (or wireless) for computers Special Req.: Solid floor with minimum floor vibration for high density shelving. **********
